PLANNING THE INSTALLATION

Before starting, plan the radio installation carefully so that it will be:

•safe for the operator and passengers.

•convenient for the operator to use.

•neat.

•protected from water damage.

•easy to service.

OPTION INTERCONNECTION DIAGRAM

Interference with Vehicular Electronics - Electronic fuel injection sys-

tems, electronic anti-skid braking systems, electronic cruise control sys-

tems, etc., are typical of the types of electronic devices which may be

prone to malfunction due to the lack of protection from radio frequency

energy present when transmitting. Ifthevehicle containssuchequipment,

consult the dealer for themake of vehicleand enlist his aid in determining

if such electronic circuits will perform normally when the radio is trans-

mitting.

WARNING

Figure 1 - MDX Components and Mounting Hardware

•out of the way of auto mechanics.

•out of the way of passengers.

It is suggested that theradio beinstalledby oneofthe many authorizedGeneral

Electric Service Stations located throughout the United States. These experienced

service stations can provide a proper radio installation and make any final adjust-

ments that may be needed.

Be careful to avoid damaging some vital part (fuel tank, transmission

housing, etc.) of the vehicle when drilling mounting holes. Always check

to see how far the mounting screws will extend below the mounting

surface before installing.

CAUTION

Ifpilotholesmustbedrilled,removeallmetalshavingsfromdrillingholes

before installing screws.

CAUTION

Radio installations in vehicles powered by liquefied petroleum gas must

conform to the following requirements.

WARNING

EQUIPMENT REQUIRED

The equipment required for installing the MDX Mobile Radio is listed

below:

•Electric drill for drilling mounting holes.

•Drills and circle cutters as follows:

•No. 31 (1/8-inch) drill for No. 8 self-tapping screws.

•No. 27 (9/64-inch) drill for No. 10 self-tapping screws.

•5/8-inch drill or circle cutter for power cable.

•3/4-inch circle cutter, hole saw or socket punch for antenna (op-

tional).

•Phillips and flat-blade screwdrivers, and 1/4-inch and 5/16-inch hex-

head drivers for mounting screws.

•No. 15 Torx® driver (ST0606).

•No. 15 Torx® tamper-proof driver (ST0618) if latch security screw

(supplied in hardware kit) is used.

•No. 25 Torx® driver (STO610).

•POZIDRIV® driver for mounting screws.

NOTES

Figure 2 - Typical Hump Or Dash Mount

For passenger safety, mount the radio securely so that the unit will not

break loose in the event of a collision. This is especially important in

station wagons, vans and similar type installations where a loose radio

could be extremely dangerous to the vehicle occupants.

WARNING

INSTALLATION IN VEHICLES POWERED BY LIQUEFIED (LP) GAS

Radio installation in vehicles powered by liquefied petroleum gas with the

LP-gas container in the trunk or other sealed-offspace within the interior of the

vehicle must conform to the National Fire Protection Association StandardNFPA

58 which requires that:

•Space containing radio equipment shall be isolated by a seal from the

space containing the LP-gas container and its fittings.

•Outside filling connections shall be used for the LP-gas container.

•The LP-gas container space shall be vented to the outside of the vehicle.

INSTALLATION

RUNNING CABLES

To assure the feasibility of the planned cable routings. it is suggested that the

cables be run before mounting the radio. Be sure to leave some slack in each cable

going to the radio so that the radio may be pulled out for servicing with the power

applied and antenna attached.

Try to route the cables away from locations where they will be exposed to heat

(exhaust pipes, mufflers, tailpipes. etc.). battery acid, sharp edges, or mechanical

damage or where they will be a nuisance to automobile mechanics. the driver, or

passengers. Keep wiring away from electronic computer modules. other electronic

modules and ignition circuits to help prevent interference to these components and

radio equipment.

In addition. try to utilize existing holes in the fire wall and trunk wall and the

channels above or beneath the doors. Also, channels through door and window

columns that are convenient for running cables may be used, unless planning to

install rigid or flexible conduit in which to run the cables.

Power And Ignition Cable

The power cable consists of a red lead, an orange lead, a black lead, a 3 pin

systemsplug.anda setoffusesandfuseholderstobeinstalledasindicatedinFigure

To install the power cable, drill a 5/8 inch hole in the firewall for the cable run

and insert therubber grommet. Startingwith the plug end of the cable atthelocation

of the radio, run the three cable leads through the hole. Secure the cable at several

locations within the engine compartment.

To install the fuses:

1. Cut off 12 to 18 inches from the red and orange wires.

2. Strip back theinsulation approximately 3/8 of an inch oneach end of the wires.

3. Lubricate the wire tips with liquid soap to insert the wires into thefuse holders.

Pull the wire ends through the small opening at the end of each fuse holder

section and crimp a fuse connector to each wire.

NOTES

Figure 11 - Mounting The External Speaker

Figure 3 - Power Cable

4. Push the prepared fuse connectors into each section of the fuse holders. Place

the fuse into a fuse holder section until it seats within the connector. Connect

the fuse holder sections to insure a tight fit and connection.

NOTE

In some installations an additional noisesuppression filter such as option

PMPD1A (19A148539G1) may be needed for satisfactory performance.

NOTE

With some accessory points, the voltage only drops when the ignition

switchisintheSTARTposition.Aconnectionpointshouldbeusedwhere

the voltage is completely off when the ignition switch is in the START

position.

Certain problems may be encountered when accessory equipment is

connected to the ignition or accessory lines of the vehicle, where these

lines may have large filter capacitors or a leakage path present.

If the radio does not turn off within a reasonable amount of time after the

ignition is turned off, first try a different accessory or ignition sense pick

up point in the vehicle. Many vehicles have more than one circuit that is

switched by the ignition switch, and one may be available that does not

have large filter capacitors or a leakage path present.

If a different pickup point cannot be found, then add a 470-ohm 1-watt

resistor from the ignition sense pick point to ground. This will discharge

thecapacitor(s) or reduce the leakagevoltage toa lowvalue.Currentdrain

through this resistor will be minimal (less than 0.03A) when the ignition

is switched on.

CAUTION

Connect the orange fused lead to the positive (+) battery terminal, and black

to the negative (-) battery terminal. Always locate the fuse as close to the battery

as possible.

Connect the red fused lead to the ignition on" sense point (preferably an

"Accessory" point on the fuse panel that is switched on when the ignition switch

is in the accessory position and in the "run" position). Locate the fuse as close as

possible to the accessory point.

Figure 10 - External Alarm Relay

EXTERNAL SPEAKER KIT - OPTION PMZM1K

The external speaker kit includes a speaker (option PMLSIF) and an external

speaker cable (option PMCC9M). External speaker cable (option PMCD1W) is

available for use with this kit to place the external speaker up to 16 feet further

away from the radio. Installation of this kit requires the option cable kit - option

PMD7Z.

1. Mount the speaker so it is directed to the operator but does not cause interfer-

ence with his vision. It also should not present a hazard in the event of an

accident. The speaker may be mounted on the lower edge of the instrument

panel, the fire wall, or above the windshield in some trucks.Use the mounting

bracket as a template for locating the mounting holes, and mount the speaker

as shown in Figure 11.

2. Install the option cable PMCD7Z if not already present.

3. Pins are supplied on the ends of the external speaker cable option PMCC9M.

Push these pins into sockets 2 and 9 of the connector housing supplied with

the option cable. Refer to Figure 8 and Table 2.

4. Plug the connector housing into P2 of the option cable.

5. Connect theplug end of the external speaker cable to the speaker. If installing

the external speaker cable option PMCDIW connect it between the speaker

and the plug end of the external speaker cable option PMCC9M.
